Document Type and Number:
Japanese Patent JP4563524
Kind Code:
B2
Abstract:
A method for producing hardened parts of steel from an air-hardening steel comprising the steps of heating the steel is heated to a temperature above 1,100° C., hot-working the steel parts until they reach the A1 emperature, cooling the steel parts in air to about 280° C. under simultaneous thermo-mechanical sizing treatment, then cooling the steel parts in air to room temperature, stress relief treating the steel parts at 150-250° C., and hard-machining the steel parts.
